Patent DE-1811530-A1 (DE)
Title: Separating branched from unbranched alkenes by
Inventor: JOHN IAMPSON ROY
IPC: C08L23/16
Filed: 1968-11-28
Abstract: Unbranched and branched alkenes are separated by bringing a mixture of these alkenes into contact with a dimerisation catalyst, consisting of a transition metal and/or a compound of a transition metal on a carrier; the branched alkene is dimerised under these conditions, and the dimer can be separated from unchanged unbranched alkene. The method is of especial use in separating isobutene from unbranched alkenes, such as butene-1 and/or -2; such mixtures are formed in cracking processes. The isobutene dimer is useful in the production of benzine and as an intermediate, the residual unbranched alkene can be dimerised or disproportionated to C6-8 alkenes which are raw materials for the preparation of softener alcohols by the OXO process.

Title: Wall cover in form of plaster or panels - contains embedded pieces of broken waste glass for producing optical effects
Inventor: SCHNEIDER ALOIS
IPC: E04F13/08
Filed: 1973-06-13
Abstract: The broken waste glass is considered as a cheap embedding material. Coloured broken glass pieces of uniform size are embedded into the wall covering material. The exposed broken glass surface produces optical effects on illumination. This application also makes use of waste material the disposal of which is difficult. The more varied and irregular the shape and colour of the individual pieces of glass the greater the visual effect due to the random reflection of light from the irregular surface of the pieces of glass.

Title: Blast furnace coke mfr. - from greater part of briquetted noncaking coal mixed with some coking coal
Inventor: STRUNZ DIETMAR DIPL ING
IPC: C10B57/04
Filed: 1973-06-26
Abstract: Large coke for blast furnaces can be produced from charges which need not consist of a preponderant proportion of coal with a high coking power. The charge consists to 30-35% of coal which is capable of producing large furnace coke, and to 65-70% of coal without that property. The latter is however, in briquetted shape. The two components are mixed, poured into a coke oven and carbonised in the usual way. This permits the use of more non-caking coal without affecting the yield of a good blast furnace coke. The costs for the coke prodn. are reduced and a high bulk density in the oven and a high coke oven throughput are achieved.
